Martian terrains are represented as a series of drainage basins, regardless of the historical presence or absence of actual fluid flow. A statistical analysis of each drainage network, computationally extracted from an underlying topography based on the MOLA data, yields a network descriptor, a compact, numerical characterization of a network. These descriptors are used to compare different mar...

As water erodes a landscape, streams form and channellize the surficial flow. In time, streams become highly ramified networks that can extend over a continent. Here, we combine physical reasoning, mathematical analysis and field observations to understand a basic feature of network growth: the bifurcation of a growing stream. We suggest a deterministic bifurcation rule arising from a relations...

Altogether 327 valleys and their 314 cross-sectional profiles were analyzed on Mars, including width, depth, length, eroded volume, drainage and spatial density, as well as the network structure. According to this systematic analysis, five possible drainage network types were identified such as (a) small valleys, (b) integrated small valleys, (c) individual, medium-sized valleys, (d) unconfined...

In GIS and in terrain analysis, drainage systems are important components. Due to local topography and subsurface geology, a drainage system achieves a particular drainage pattern based on the form and texture of its network of stream channels and tributaries. Drainage pattern recognition helps to provide a qualitative description of the terrain for analysis and classification and is useful for...

In watershed mountain basins, affected in the last decades by strong rainfall events, role of debris-flow and debris flood processes was investigated. Morphometric parameters have proven to be useful first-approximation indicators discriminating those processes, especially large areas investigation. Computation morphometric 19 basins western side valley Vallo di Diano intermontane basin (southe...

Introduction: Voxel based morphometry is a type of statistical parametric mapping that can be used to investigate the effect of diseases such as epilepsy, Alzheimer's disease and Parkinson's disease or other agent such as skills on brain structure (white matter, gray matter and cerebrospinal fluid). The aim of this study is evaluate the effectiveness of this method in detection of differen...

OBJECTIVE Morphometrically analyze the cells nuclei of the basal layer of the prostatic glandular epithelium in 20 patients aged between 57 and 85 years presenting benign prostatic hyperplasia with severe symptoms, catheterized or not. MATERIALS AND METHODS Patients with score of severe prostatic symptoms (with indication for transurethral resection of the prostate) were distributed according...

concerns about nitrate pollution in groundwater and downstream systems cause development of surface water management system to reduce losses of agricultural drainage water nitrate in subsurface drainage using subsurface irrigation from existing drainage lines, drainage water during the growing season and out of season is controlled. the overall objective of this study was to evaluate the effect...

Flood is number one Indonesian natural disaster in the last 10 years and its occurrence at Manokwari frequently reported. Biophysical condition playing a key role carrying capacity of this catchment area.This study to determine biophysical characteristics Wosi Watershed manage mitigate flooding Manokwari. Spatial analysis field observation methods were used collect data. variables are rainfall,...
